[MPlayer-users] DGA scaling problems

[Risto A. Paju]

The current CVS version of MPlayer has problems with fullscreen DGA on my
system. It seems the program chooses the wrong resolution, thus leaving
a lot of empty space on the screen. Sometimes the resulting aspect ratio
is wrong.

The problem has been in the CVS for some time. I have a version from June
4th which works fine, but it lacks some of the new codecs.

System info:
Linux-2.4.22-ck1
Mandrake Cooker
GCC 3.3.1
binutils 2.14.90.0.5
GLIBC 2.3.2
XFree86 4.3

Hardware:
Matrox MGA G100 AGP, using the mga driver of XFree86
